21.78 Flood of record of 1967. Highest record level of water at this point.
18.67 In August 1986...a crest of 18.7 feet was associated with the worst flooding on the Salcha River since the great flood of 1967. Long time residents on the Upper Salcha said that the crest came within inches of the 1967 crest. Aerial reconnaissance on Aug 23 showed many residences on the Lower Salcha and many cabins on the Upper Salcha to be flooded. The Salcha campground was completely flooded. Vehicles left there were in deep water. In spots...water was 5 feet deep in the subdivision below the bridge.
14 Flood stage at left bank of campground. Roads between the hwy and the Tanana River start to have water on them.
